Application filed Karen 3 To ail "whom it may concern:

Be it known that T. Pam LEoNmn BAU- our, citizen of the-French Republic, residing at Paris; Department of the Seine, in

6 France, have invented certain new and useful Improvements in Bottling Mineral Waters; and'I'do hereby declare the following to be a 1111, clear, and exact description ofth'e invention, such as will enable others 10 skilled in the art to which it appertoins to mike and use the same.

In the practice of bottling mineral waters, it has been customary to clean and sterilize the bottles or; containers and then fill the lat- 11 5. .mr with ,anwinnocuous gas, such. as. carboni acid gas, to prevent contamination of the bottles, such" as, might be produced by contactwith atmospheric air, priorto the filling operation. Thetpresence of this excess of carbonic acid gas h'as beeen found\objecti0nable and deleterious, incertain cases in which" mineral: water's carry constituents, which would be obviously aflectedby such excessof carbonic'acidgas. 25, The present invention ha'sfor its object to provide-an" improved process of bottling mineral waters and the like, so that the properties'of the mineral water will be unchangedfin spiteofthe presence of carbonic 3Q acid inthe container.

To this endthe inuenti on comprises reducing the' pressure' of the'guseous medium in the'bott-le occonta-iner; priorto the admission'of the water or the like to the container, 86 until the gaseous pressure in the container is equal'touthe pressure or tension of the gas, whichxis' maintained; in solution or suspension'in the-wstermr the liquid.

i There arecertain medicinal Waters which 60 contain useful solid matters, such as colloidal iron, which matters are maintained in their state of suspension or-equil.ibriuin "because of the presence of particular quantities of free carbonic acid. It is, therefore, advisable, for the purpose of preserving the composition of said waters ithout'impairment not to add carbonic acid to thesame.

as this makes the use of the process desclibed impossible. Furthermore, it is necessar to avoid the disappearance of the smel quantity of free carbonic acid, as its elimination would produce precipitation of the solid matters.

Ia order to carry out this bottling of the in water with incompletefrarefaction of the ear onic acid or other gases with which the ho 1e is filled at atmospheric pressure the StllC bottle, instead of being connected di rectly to the vacuum, tank when in place on the machine connected to an auxiliary tank in which as. perfect a vucuum us possi ble'has been produced. The volume of this auxiliary tank is such that the carbonic acid supplied to the bottle at atmospheric pres 5 su'rc assumes the desired pros-sure when the Water enters the bottle by expanding in the bottle and the auxiliary tank. in th'eex- :unple previously mentioned, when it is de sired to arrive at a pressureoi" 0.2 atmosphercs during the hottlinc er the water, and assuming that the volunte of the bottle is one liter, the capacity of the auxiliary resets mix is um defour liters. T2318 the gas con tained in the bottle when the water isin- 96 'troduccd into the latter willpass entirely into 'thef'afui'riliary tank at the end of thebot- -flit-1g.operation and will thus occiipya space four times greater than that of vthe bottle.

Its'pressure'will be mama; therefore to 100.

- slightly higher than that at the beginning; 10;

However, it is necessary, in order to avo d any. disassociation of materials in the water, that the'pres'sure never fall below 0.2 atmospheres and'the rapidity with which the 0peration-takes place is such that the me'xi- 1 10 v van mum pressure is attained only at the end of the operation, and thus the solution of .even

a small proportion of the gas 18 mpossible.

In the accompanying drawings Figures 1 an 2show, by way of example, two constructions of apparatus for carrying out the process.

In the device shown in Fig. 1, the bottle 18, which has been previously filled with carbonic acid in the manner above described, is placed on the bottliri 1 machine provided at its upper portion wit a casing 9 and with two cocks fi-and 16, the cock Bbeing in the pipe 21 which leads from the ca: mg to the:

va'cuum tank 22, and the cock 1E oein'g in a pipe which 15 connected .to ti source of supply ofniineral water.

' The bottle 18 is placed on a vice which locates under a rubber washer of the casing 9, and thence under a casing of the corking machine without permitting thev mouth of the bottle to come in contact with the air, Specifically, the bottle 18, which is filled with carbonic acid, is placed .on the disk 25 of the bottling and corking machine and by means of thecock 8 and the tank 22, g a, partial vacuum is instantaneously pro- 'duced in the bottle and the cock is closed.

Iihe cock 16 is then 0 ened an a suction is 30 produced, owing to t e difference of pressure, and the Water from the source passes through the pipe 20 into the bottle and fills the latter.

' Thiswater is conveyed to'the bottle in the following manner g A pure tin siphon 24 is provided, which conducts the water from the source 25 at a depth of, for instance, two meters, into a basin 26, because of the difference in pressure, the basin 26 being at level from three to three and one-half meters lower than that of the source 25. This siphon passes'through the bottling room at a height of about three meters from the floor, actual practice.

From the upper portion of the siphon, the pipe 20 branches, which pipe is also of pure tin and descends vertically above the bottle, opening into the casing 9. Y This pipe includes a portion 29-, in'the interior of which a check-valve -28 is located, which valve closes under an excessof pressure'in the pi e 20. -At tlie point of intersection of the B- sha ed pipe,with the-siphon, a three-way 000* 23 is arranged by means of which the {low in,the siphon may be deviated at will 'towar the bottle until the latter is complete filled. The cock may then be turned so that the water will flow again through the siphoni This arrangement makes it, therefore, possible toalways have available running water-for bottling, which water is brought to the highest point. in the siphon by natural pressure, and thence passes by the force offravity into the bottle.

The top 0 the siphon is arranged at least "t rec meters from the ground, so that the pc 20 may be approximately two meters. his pipe is of such diameter that it may retain in this length, about one liter of water, after the-bottle has been filled with water.

When the water to be bottled contains a certain quantity of free carbonic acid, as in the case of Forges water, a portion of the gas dissolved in the water expands in the bottle, owing to the vacuum therein. The

'column of water in the pipe 20, which is in practice about two meters high, as aforesaid, rests on the gases which havea tendency to escape. This easily compresses the gases:

and in passing therethrough dissolves them, so that the water retains its entire gaseous content. As soon as the filling operation has been completed, the cook 16 is closed-and the pipe 20 remains full of water until the cock is again opened for the subsequent filling of a bottle. The reestablishment of the flow of the water in the siphon after each bottle is filled prevents the water from becoming contaminated.

' In order to more fully insure the exclusion i of the air during the movement of the bottle from the fillin point to the corking point, the mouth of t e bottle may be moved in an atmosphere of carbonic acid contained in a suitable hood, not shown.

Fig. 2 discloses a modified apparatus for arrying out the method who 1 medicinal waters, comprising useful solid matters and carbonic acid, are bottled. Referring particularly to this figure, ti 5 water circulates in a siphon 24-27 Which is arranged between the source 25 and the basin 26 on the lower level. A tank 221s 111 open communication with a vacuum pump, not shown,

which works continuously. This tank is connected by means of a pipe 31 having a cook 32 t erein, to a disk 33, on which is placed and packed an auxiliary dome 34. The pipe 31 asses through the disk 83 and rises to a 'su cient height within the dome, so that itwill not be submerged, when, owing to carelessness of the operator, the water rises in the dome. through the center of the d sk 33 and terminates at the. casing 9. This pipeis pros vided with a cock 8 which is located between A pipe 35. extendS the casing 9 and the dome 34. A pipe 37 extends downwardly from the dome 34 but does not pass beyond the upper face oi the disk 33 and is provided with a suitable stop cook. The water inlet 20 is branched di reotly from the siphon 2427 and ternn mates in the casing 9, cominunicatingwith the pipe 35 at this point. The water inlet pi. 'e 20 is provided with a sto cock 16.

en the water is bottled y the apparatus disclosed in Fig. 2, the operation is. as follows Previous tests of the water which is to be bottled having showxi the quantity of dissolved carbonic acid therein, a dome 34,

' placed on the, disk The bottle 18 LS remaining located on the disk 25 of the machine having been previously filled with carbonic acid at atmospheric pressure. The volume of the selected dome 34 is such that utter the carbonicacid, which fills the bottle 18 at the atmospheric pressure, has passed into the dome from the bottle, its pressure is reduced to such a point that the water which, in the meantime has been introduced into the 'bottle, contains only the carbonic acid which it contained before its introduction into the bottle. he dome having been put in place,- the cock is opened, the cooks 8 and 37 closed. By this operation, a vacuum is produced in the dome 3i, and then the cook 32 is closed. The bottle 18 filled with greater portion of the carbonic acid at atmospheric pressure is placed on the disk 25, the neck being brought under thecasing 9. The cock 8 is opened, the cook 16 remaining closed and the ca onic acid contained in the bottle passes into the dome 341. The cook 16 is then opened and the water fills the bottle 18 expelling what remains of the carbonic acid.v The entire volume of the gas brought into the bottle by the entrance of the water is forced into the dome 34 and its pressure, when it occupies this dome, is equal. to the pressure of the gas within the water. After theliottle is fi'lled, the cock 1.6 is closed.

If, owing to the late closing of the cock 16, the water gets into the dome 34 through the pipe 35, it will fall back on the disk 33 and the cook 37 may then be opened to drain the dome. The disk 33 is so constructed that it may receive domes of various ,operation may sizes, so that they may be interchanged, as the requirement of the final pressure of the gas varies. I

\Vith the process described, the bottling be carried out, so that the Water will contain all of the carbonic acid after the bottling operation that it contained before the same, and furthermore, all foreign matter will be excluded from the bottle.

I claim:

l. The method of bottling mineral waters and the like, containing a gaseous constituent, which consists in reducing the pressure in. the container to a point not lower-than the tension at which the gaseousconstituents of the water will escape, and then admitting the water to the container. I

2. The method of bottling mineralw aters and the like containing a gaseous constituent which consists in filling the container with a gaseous medium, then reducing the pres sure of. the gaseous medium in the container to a point not lower than the tension at which the gaseous constituents in the water will escape, and then admitting the water to the container.

3, The method of bottling mineral waters an the like containing a gaseous constituent I w "ich consists in.v filling the container with carbonic acid gas, then reducing the pressure of the carbonic'acid gas in the container toga point not lower than the tension at which the gaseous constituents in the water will escape, and then admitting the water to the container.
